Document Type and Number:
WIPO Patent Application WO/2019/123977
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for manufacturing a stator of a dynamo-electric machine for which it is possible to make coil ends more compact. The present invention is a method for manufacturing a stator that comprises a stator core, and a stator coil to which are connected end parts of a plurality of approximately U-shaped segment coils inserted into slots of the stator core, wherein the invention is characterized in comprising a coil-twisting step for twist-shaping the end parts of the segment coils using a twisting jig 600, and, once the end parts of the segment coils have been inserted in groove parts 610 of the twisting jig, twist-shaping is performed in the coil twisting step by applying a load to the segment coils so that impressions of edge parts 620 that constitute a part of the groove parts 610 are formed on the segment coils, the edge parts serving as twist support points.
